VAGUUIVI'AGITATOR FOR WASHING MACHINES.

Application sied January 14, 1922, serial My invention relates primarily to an agitator or dolly for use in a machine of the oscillating dolly type and among the objects thereof are to provide an improved washing machine agitator; to provide a structure of the character described having suction cups adapted to act on 'articles being washed in a( manner somewhat similar to that of a re-' ciprocating suction cup device; to provide an oscillating dolly With suction cups to assist in forcingwater-through the clothing being washed; and such furt-her objects, advantages and capabilities as will later more fully appear. f

My invention further resides in the combination, 'construction' and arrangement of parts illustrated in the accompanying drawing, andwhileI have shown therein a preferred embodiment I desire the same to be .understood as illustrative only and not as limiting myinvention.

ln the accompanying drawing: y

Fig. 1 is an elevation showing my improved agitator.

Fig. 2 is a vertical section taken substantially centrally of the device as shown in Fig. 1.

Fig. 3 is an elevation similar to Fig. 1 but taken in a direction at right angles thereto.

Fig. 4 is a section similar to Fig. 2 but taken in a direction at right angles thereto.

Fig. 5 .is a view from the under side of Fig. l, but showing parts of the structure in section.

Referring more in detail to the annexed drawing, numeral 1 designates the usual power driven agitator-shaft, which may be circular or angular in cross'section, depending upon the construction of; the machine with which this device is to be used. Numeral 2 designates the body plate of the agitator having substantially centrally thereof a boss 3 through which passes a securing means 4 to secure the' shaftl to the plate 2.

' Webs 5 and, 6 are provided with lflanges 7 and 8 to assist in preventing them from rocking when secured to the plate 2 by means of projections 9. The web 5 has its liange 7 continued around the ends as shownat to serve as reinforcing means for the strengthening of the web. Web 5 has an aperture 11 therethrough which is bordered by a flange 12 on each side of the web and webs 6 have each one end such as 13 shaped to fit into the perforation 11, as shown in Figs. 4 and 5.

No. 529,131. Renewed March 14, 1927.

These ends 13 are preferabl considerablycA heavier than the webs and t erefore assist 1n furnishing a secure bearing to prevent distortionv and breaking of the parts in use'. On each side of each free end, the webs are provided with flanges which form cups 14 and l5, the former being. substantially circular and the latter being somewhat flattened on vone side to lit closely against Vthe under face of the plate 2, as shown most clearly in Fig. 4'. 65

It will be obvious from the foregoing description that, as the agitator shaft 1v isos- 1' cillated, first one set of cups 14, 15 will'act upon the clothing in the machine, and then the other set will actthereon -as the agitator .is oscillated in the opposite direction. It will therefore be clear that these cups 14 and 15 will force water through the clothing, besidesxpe'rforming the lordinary function of oscillating the clothing in the. machine in the manner of dollies provided with pegs.

I t is of course understood that the specific description of structure set forth above mayl be departed from without departing from l the spirit of my invention. Y 30 Having now described my invention, I i claim 1. In a dolly, a substantially imperforats member adapted to be oscillated about an axis, said member having a blade extending therefrom, said blade having a suction cup thereon disposed transversely tothe plane of said member.

2. A dolly comprising an oscillatory plate having downwardly extending projections, and laterally directedsuction cups'on said projections.

3. A washing vmachine agitator comprising an agitator shaft, a plate secured thereto, and f agitator members extending transversely of one face of the plate and having cups thereon facing laterally.)

4. lA washing machine agitator comprising an agitator`shaft,a plate secured thereto, and agitator members having suction cups on opposite faces thereof extending substantially perpendicularly to the body of the plate.

.5. A washing machine agitator comprising an agitator shaft, a plate secure and agitator members having suction cups on opposite faces thereof extending substantially perpendicularly to the body of the plate, one of said members comprising a. webmember having an aperture therethrough 1 10 dthereto, v

and the other agitator members comprising Webemembers each provided at one end with a portion adapted to'fit into the aperture in vthe first named web-member.

6. ln a dolly, an oscillatory support haw ing projections rigid therewith, and'suction cups being formed in said projections remotely of the axis of oscillation of said support.

7. An agitator for eecting washing operations, comprising a substantially imperforate disk oscillatable about an axis and formed with a relatively deep member projecting from said disk,.said disk having a cup-shaped portion thereon operative to press upon the material to be washedwhen moved in` one direction and to create a suction when moved in the opposite direction.

8. AniagitatorV for eecting washing operations, comprising a substantially imperforate disk oscillatable about an axis and cupshaped members rigid with said disk for.

movement therewith during the alternately rotary movements thereof, said-cup-shaped portions operative to press upon thef material to be washed when moving in one directionI and to create a suction when moving in the oppos1ted1rect1on. I

9.. A dolly comprising an oscillatory plate formed vwith transversely arranged suction cups at the border of said plate remote from lthe axis ofl oscillation of said plate.`

10. A dollyv comprising. a vertical shaft, a disc iXed to vsaid shaft, and suction cups-fast withsaid disc, near the. periphery -of said disc. 11. A dolly comprising a shaft, a plate lixedto the shaft, and' suction .cups depending" from the edge portions of the plate.Y A

12. A dolly comprising an oscillatory disk having transversely disposed suction elements thereon and yarranged at var-iantdistances from the axisofloscillation of said 13. A dolly comprising an oscillatory disk having suction elements thereon arranged at variant distances vfrom one surfaceof said disk and also arranged at different distances also laterallyof the disk.

14. A dolly comprising an oscillatory disk having transversely disposed suction elements thereon arranged to travel in different horizontal the disk.

A15. A dolly having suction cups connected therewith, said cups being positioned in difplanes during the oscillation of,l

ferent horizontal planes so as to travel in dif- 1ferert horizontally disposed paths in the 16. -A dolly comprisinga vertical oscillatable shaft and carrying-a plurality of suction cups having their open mouths disposed substantially transversely to the axis of the fshaft and arranged in different horizontal webs carrying suction cups adapted to osv cillate in horizontal lanes.

19. A dolly compri ing a vertical oscillatable power driven shaft having substantially flat webs extending horizontally therefrom, said webs being of different widths, and carryingsuction cups disposed in di'erent horizontal planes.

20. A dolly comprising'a plate oscillatable in a horizontal plane and suction cups having their open mouthsA disposed at an angle to the planelofthe plate and voscillatable 1 therewith.

21. A dolly comprising an oscillatory plate, vertically disposed webs carried by the plate and suction cups carried by the webs.

22. power driven oscillatable shaft, vertically disposedi webs extending from the shaft to oscillate in a horizontal plane and suction cups carried by the webs.

23. Apower driven oscillatable'shaft, four webs radially carried by the shaft` each of said Webs carrying suction cups having their open mouths lfacing atan angle to the axis of oscillation of the shaft.

24. A dolly comprising an oscillatory disc*l provided with suction elements having their l axestransversely disposed.

25. A dolly comprising a shaft and an oscillatory disc providedwith suction elements having their axes transversely disposed with f.. 'reference to said shaft. In witness whereof, I hereunto subscribe my name to this specification.
